What’s the Difference between the FC Part Number Suffixes -PP, LP, MP and HP?
The FC Series Fuel Sell Humidifier has a number of suffixes that call out the construction type. Here is a list of them:
MP – Molded Polypropylene.
PP- Polypropylene. The PP suffix refers to machined Polypropylene, and is obsolete for many sizes, being replaced by MP (molded Poly). It is still current for FC150 and the FC600.
LP – Low Pressure molded End Caps and Shell (sizes FC200, FC300 and FC400)
HP – High Pressure molded End Caps and Shell (sizes FC200, FC300 and FC400)
